You need to adjust the image source path to point to the correct location relative to your /USERS/Profile.html file, what you are looking for is '../' which will navigate up one folder.
I am assuming this is what your folder/file structure looks like -
BLOG/
- Feed.html
- images/
- image1.jpg
- image2.jpg
- USERS/
- Profile.html
Based on structure, your code will be -
<img class="image-style" src="../BLOG/images/image1.jpg">
What the code does is, go from the current folder - 'USERS' with file 'Profile.html' open, up one folder to - 'BLOG', down one folder into - 'images' and then the actual image file.
